Any insight would be helpful - Mike dogfriend 11-01-2003, 12:52 PM Im not sure about the 99 OHV engine, but my 97 OHV does not have a knock sensor. The 4.0 SOHC engine does have a knock sensor. Check out this thread, in particular the TSB that I attached near the end of the thread: Is that true? (http://www.explorerforum.com/forums/showthread.php?s=&threadid=68353&highlight=knock) Rhett 11-01-2003, 09:58 PM I don't think any of the OHV Explorers ever had knock sensors. SOHC trucks did/do though. |
